scmn | 2500/3500 frames are the same on longbeds models. With the standard bed model the 2500 frame does not have the bushings for the overload spring perch, while 3500 frame does.
If a 2500 is ordered with NHT Max Tow Package then the 2500 gets the 3500 leaf spring and shock package plus the 12in rear axle; standard beds also get the 3500 frame as part of NHT to accommodate the overload springs. | |
